If a principal's goal is to improve the overall quality of reading instruction in his school, this guide can help him identify the most critical changes that must be made. It describes the types of instruction and leadership activities necessary to help all children become proficient readers in elementary school. It does not contain all the information needed, but refers a principal to additional readings in specific areas to enrich his knowledge. He should think of it as a "quick start" guide for a school-level instructional leader. It can point him in the right direction, but it can only provide a taste of the knowledge needed to be a successful literacy leader in his school. The authors encourage principals to become familiar with the ideas in the guide, and then embark on a program of systematic study to fully prepare for this challenging and rewarding task. This guide is based on scientific research on reading and reading instruction, as well as on studies of successful schools and interviews with successful principals.
